Valco(R) Pre-Column Filter

In-line installation. Efficient, low dead volume filters protect your columns from particles without reducing column performance. The replaceable 1/8 in. frit has 0.5 mum pores to protect 3 mum or 5 mum column packings, the replaceable screen has 2 mum pores. Choose the frit filter for higher filtration capacity (most applications) or the screen filter for less dead volume (e.g., with microbore columns). Use with 1/16 in. O.D. tubing; 1/16 in. fittings included.
